Our story

A reef in crisis.
A project born from love.

In April 2020, a crown-of-thorns starfish outbreak devastated our house reef. We manually removed every COTs, launched our first coral replanting experiment, and within a year average coral growth reached 10-20 cm. We never looked back.

Today, 131 frames and 50 nursery sites later, Katembe's mission is to teach guests as well as local communities to actively participate in hands-on reef restoration and be part of our dear project.

We sit at the heart of the Coral Triangle — home to 76% of the world's coral species and 2,000+ fish species. What we do here matters for the entire planet.

What we are building

Our goals for the reef

Protect marine diversity

Restoring coral habitats supporting hundreds of fish species native to the Coral Triangle.

Coastal protection

Healthy coral reefs act as natural barriers protecting our coastline from erosion.

Ecosystem restoration

Growing thriving ecosystems that sustain local fishing communities and livelihoods.

Climate adaptation

Cultivating heat-resilient coral varieties adapted to warming ocean temperatures.

Educate locals

Training local divers and community members as skilled reef stewards.

Local job opportunities

Every Impact Partnership hires and trains a local coral restoration assistant.

The coral restoration workshop-week was everything I could dream of and more. Never have I felt so warmly welcomed. Sandra and her team balanced coral studies, hands-on restoration, and free time perfectly.
